NURSING BOTTLE.

Lati.

Application filed April 21,

To all whom if may concern:

Be it known that I, WILLIAM S. ALVEY, a citizen of the United States, residing at the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Nursing Bottles, of which the following is a specification.

The principal object of the present invention is to provide a sectional, protective jacket for nursing-bottles so designed that the same may be readilyremoved when it is desired to sterilize such bottles. A fur ther objectl is to provide a sectional, protective-jacket for nursing-bottles ,so designed that a conventional nipple may be clamped between the bottle mouth and the upper section of saidjacket to preclude possibility of the nipple being accidentally displaced.

The invention consists of the improvements hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof and in which Figure 1, is a view in central section illustrating a nursing-bottle equipped with a' protective-jacket embodying features of the invention, and j Figure 2, is a fragmentary view, in section, illustrating the manner of assembling the jacket parts.

In the drawings 10 designates a conventional glass nursing-bottle to the'neck of which is usually applied a rubber nipple as 11. An infant, in nursing, is apt to disengage the nipple from the bottle so that spilling of the bottle contents takes place. Frequently an infant causes breakage by tossing the bottle away. By the construction of parts about to loeA described both of these disadvantageous features are eliminated. 12 designates the body part of a sectional protective-jacket, preferably of hard rubber, although other materialtas fibre, may be employed. The part 12 1s shape( and proportioned to snugly fit around and completely cover the body portion of the bottle including the bottom thereof. That portion of part 12 adjacent to the rim thereof is screw-threaded as at 13 to receive thc A Specification of Letters Patent. ygwgmtd Jun@ 69 ggge 1920. Serial No. 375,614..

screw-thread portion 14 of a removable neck partl.y The neck part is shaped and proportioned for snugly engaging around the neck of a nursing-bottle and has an open outer end. The said outer end is provided with an internal, annular groove 16 which receives the annular flanged portion 17 of the conventional nipple 11. In practice the nipple fiange is caused to seat withinthe groove 16 by passing the nipple up through the neck-part 15 before said part 15 is screwed to place upon the body-part 12. When the neck and body parts 15-12 are in co-operative engagement the major portion of the nlpple ange is in abutting relation with the riin of bottle 10 and is firmly clamped thereagainst by the flanged portion 19 of the neck-part 15.

If desired a cap 18 may be employed for attachment to the neck-part 15 for protecting the nipple 11 when the nursing-bottle is not 1n use.

WhatI claim is The combination of a conventional nursing-bottle with a sectional protective-jacket of r1gid material of which one part compr1ses an integral body-portion having a permanently closed bottom upon which said the major portion of said bottle the inner end of said jacket-part being screw threaded and of which the other part comprises an open ended integral neck-portion which completely envelops the bottle neck and a part of the bottle body the extreme outer end of said neck-portion being provided with an internal annular fiange having a convexed surface and the opposite end of said neck-portion being screw-threaded for attachment to the body jacket, there being an internal, annular groove of circular crosssecton intermediate said flange and said screw-threaded end and a conventional nipple having a flange seated within the groove of said neck-portion with the nipple proper extended through and snugly fitting the said convexed flange whereby when the jacket parts are screwed together said con- 1 vexed flange clamps the nipple flange against WILLIAM S.
